Abstract
The invention discloses a high-strength concrete square column with bundled spiral stirrups. The high-strength concrete square column with the bundled spiral stirrups comprises a concrete square column body and a steel bar framework embedded in the concrete square column body. The steel bar framework comprises the square spiral stirrup, first longitudinal bars, the round spiral stirrups and second longitudinal bars. The first longitudinal bars are longitudinally bound or welded to the square spiral stirrup to form a square reinforcement cage; the four round spiral stirrups intersect in pairs; the multiple second longitudinal bars are longitudinally bound or welded to each round spiral stirrup and the intersection area of every two round spiral stirrups to form a bundled spiral stirrup reinforcement cage which is arranged in the square reinforcement cage. According to the high-strength concrete square column with the bundled spiral stirrups, the section size of the square column is reduced, the effective use area of a building is increased, and the defect that the manufacturing process of a composite stirrup reinforcement cage assembled in an existing large-section reinforced concrete column is complex is overcome. The high-strength concrete square column with the bundled spiral stirrups is simple in overall structure, high in construction speed and bearing capability, and suitable for serving as columns at the bottom layer of a high-rise building, columns in industrial heavy workshops and piers of a large-span bridge.
Description
Technical field
The invention belongs to the vertical supporting member of building structure, be specifically related to join and restraint tie hoop high-strength concrete square column.
Background technology
Armored concrete is the most widely used material in field of civil engineering.Along with being continuously increased of building height and span,
Pillar sectional dimension in building upper part bearing structure is the most increasing, the post of more than 1 meter even up to 2 meters in skyscraper
Son is the most common, and while pillar cross section increases, in post, the number of steel bars of configuration is also multiplied, and wherein stirrup portion is adopted more
With the compound stirrup being made up of with multiple tension ribs single closed rectangular stirrup, the molding of this compound stirrup will through reinforcement metal straightening,
, there is complex process, the construction speed problem such as slowly in the multi-step process such as cutting, bending, colligation..
In skyscraper, the pillar of huge sectional dimension also can cut down effective usable floor area in building, for reducing cutting of pillar as far as possible
Face, current main flow way is to use high-strength concrete, i.e. by improving concrete strength relatively duckpin under identical load action
Size.But, high-strength concrete has ductility difference to be susceptible to the shortcoming of brittle break, can reduce the anti-seismic performance of building structure,
For overcoming this problem, solve often through the configuration amount increasing stirrup again.The increase of stirrup consumption, causes reinforcing bar to add again
Work amount and complexity increase severely, and increase concrete pour difficulty.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of simple structure, speed of application be fast, high the joining and restraint spiral hoop of bearing capacity
Muscle high-strength concrete square column.
The present invention is with the following technical scheme above-mentioned technical problem of solution:
Join and restraint tie hoop high-strength concrete square column, including concrete square cylinder and the reinforcing bar being embedded in concrete square cylinder
Frame, described framework of steel reinforcement includes square spiral stirrups, first indulges muscle, round screw thread stirrup and second and indulge muscle；First indulge flaccidity of tendon and muscle to
Colligation or be welded on square spiral stirrups and form square steel reinforcement cage；Round screw thread stirrup has four, intersects two-by-two, many second
Vertical flaccidity of tendon and muscle to colligation or is welded on each round screw thread stirrup and in the intersecting area of each two round screw thread stirrup, is formed and restraints
Tie hoop steel reinforcement cage；And restraint tie hoop steel reinforcement cage and be placed in square steel reinforcement cage.
The cross section length of side of described square column is not less than 1000mm.
The pitch of described round screw thread stirrup is 50mm～200mm, and less than 1/5th of screw diameter.
The pitch of described square spiral stirrups is 200mm～300mm.
The strength grade of described high-strength concrete is not less than C50.
Substantive distinguishing features and the advantage of the present invention are:
Tie hoop in square column of the present invention provides stronger sidewise restraint effect to high-strength concrete, effectively improves high-strength mixed
The ductility of solidifying soil, can effectively reduce the sectional dimension of pillar under certain load action, saves construction material, increases building and uses
Space；Unitary construction is simple, and the major part course of processing can use mechanical automation to complete, and speed of application is fast, and bearing capacity is high, fall
Low integrated cost；It is applicable to skyscraper bottom pillar, industrial heavy Factory Building pillar and the bridge pier of Loads of Long-span Bridges.
